Financial analysts have delineated two main categories of restaurants, each with subcategories. Full-service restaurants offer table service (with waiters or waitresses), and patrons pay for their meals when they're finished. Limited-service establishments would not provide table service, and patrons pay up front. Full-service restaurants accouruted for slightly over half of all U.S. restaurant sales in 2006 and appear to be growing a bit faster as a group than limited-service. The main distinguishing factor among full-service restaurants involves the size of the check. A fine steakhouse such as the Palm in New York City will have a substantially higher average check than a casual steakhouse like Outback only a few blocks north. Not without justification, the Palm would argue that superior food quality and service justified the higher price. Among other full-service subcategories, Denny's holds the largest market share among family-style restaurants, Applebee's leads in the varied menu group, the Olive Garden is the leader within the full-service Italian sector, Red Lobster dominates the seafood sector, while the On the Border chain leads in Outback Steakhouse.
